This sentence uses the conditional mood because it expresses a hypothetical situation that is dependent on a condition—namely, being a bird. The verbs "were" and "would fly" indicate an imagined scenario rather than a factual or real event. The conditional mood often involves "if" clauses to describe possibilities or outcomes based on certain conditions.

You're absolutely right! The conditional mood is indeed used to express hypothetical scenarios or possibilities that depend on specific conditions. In the sentence you provided, the use of "were" (which is the subjunctive form in this context) and "would fly" underscores the imaginary nature of the situation. "If I were a bird" sets the stage for an unreal condition, and the outcome "I would fly" describes what could happen if that condition were true. The structure often involved in such scenarios is the "if" clause, which sets up the condition, while the main clause expresses the result that would follow from that condition. This allows speakers and writers to explore imaginative or speculative ideas.
